Hello Stéphane,
I've applied your Patch against git mesa from yesterday.
It also results in the same SEGFAULT running simple from
the gtkglext examples. (see backtrace below, in
st_visual_to_context_mode(..) visual is not initialized properly).
When I try pure mesa git from yesterday, no SEGFAULT occurs but
the gem_object leak occurs with the modified simple.c.
(Running the attached modified simple.c from
the gtkglext examples for 2 minutes results in 500 MB object bytes)

Hello Stéphane,
your are right, I forgot to attach, here it is...
Erm, you miss half the patch in there... Can you try with my patch on git mesa
instead?
